will it test a 3 volt button battery?

I don't honestly know, but in theory it has the proper setting and the test leads can be positioned on any battery as long as the positive and negative sides are accessible so my guess is that it can. Hope this helps.

It can do 1.3-1.5 button cell only. It does have two nodes on the front that are for Lithium 3 volt batteries but it doesn't say "button" type. You charge the 1.5 size button by slipping into a slot on the right side of the charger and pressing that red button you see on the front.

You get the best indication of battery condition under load. All this tester does is provide a load and measure voltage. I expect it wold work fine for your deep cycle batteries.

This tester will not test car batteries it's designed for AA, AAA's, Button batteries, hobby batteries ,9 volt and watch batteries. For car batteries you need a tester that will put a load on it to test the capacityfor cold cranking. Hope this answers your question.

A Multimeter would work just fine to check the voltage left in a suspect battery.

Yes, there is a button to test the lights on the battery. It blends in to the case.

Yes, it should. I mounted mine in a Radio Shack project box and use it to check 12 volt batteries for my boat, trolling motor, and riding mower. Works great for that.

Yes, this would be an excellent use for this tool. Be sure to check a known power source such as a receptacle to ensure the tester is working properly.

along as it's a 12V battery, and you check one battery at a time it should work

No. Looking up at the detector you see a dim green led that is constantly on verifying that the 110 volts is connected. The detector also has a flashing red light that blinks every 30 seconds when the battery is good and a battery test button. The test button also functions as a HUSH button if pushed while the detector is chirping for a low battery condition or after a false smoke alarm. This Hush button will silence the chirping for 13 hours and can be re-pushed for up to seven days.

It has a button that switches from wired power to battery power to test that the battery is installed and charged.

Of course. It even has two terminals (+ & -) on the surface for testing 9-V batteries.

Should be able to test 6 volt battery one at a time, not all connected together.

A 3 volt "trigger" won't do anything with this. If you are referring to the relay after the count and trip is fine but this runs on 12 volts aka a 23AE battery...3 volts won't turn this timer/relay on.

You would have to use a battery tester or a voltmeter whcih will tell you if there is still a charge on the battery

i don't think that will work as you would be measuring micro voltage , you may need a galvanometer

Yes, it will charge button top or flat top batteries much larger (or smaller) than that, 3v or 3.7v (there's a little switch on the side). Fairly sturdy but no bells and whistles to it. No auto shutoff so make sure you remove the batteries as soon as it turns green. Nothing disastrous has occurred but better safe...

The battery type can be tested includes CR-P2&#65292;CR2&#65292;CR123A&#65292;CR-V3&#65292;2CR5&#65292;AA&#65292;AAA&#65292;and button cells.
